`JONATHAN BACON, OF BEDFORD,` MASSACHUSETTS.

SPRING WINDOW-FASTENER FOR WINDOW-SASHES. y

Specification of Letters Patent No. 796, dated June 20, 1838.

To all whomt may concern Be it known that I, JONATHAN BACON, of Beford, in the county of Middlesex and Stat-e of Massachusetts, have invented anew and Improved Mode of Fastening Vindow- Sashes at Any Given Position; and I do hereby declare that the following is a full and eXact description.

A metallic angle, with one leg about three inches, and the other two or more inc-hes long, with a foot on the end of the short leg, one fourth of an inch, as represented in the drawing hy the angle 6, d, e, an open spiral spring as in n, and a pivot passing through the angular point as in z'.

To enable others to make and use my invention I will proceed to describe its application and operation:

I pass the longest leg of said angle through the stile marked Z), of the window sash, as in the drawing, close under the har, o-r rail, a, in a inortise wide enough to give said angle room to play, I hed the short leg of said angle, into the edge of said stile neXtto the jamh of the window. In

the Center of said hed, I bore a hole one inch, and drop in said spring. I then press said angle' down in its place, and secure it by passing said pivot through said stile, and angular point. In the jamb of the window, I cut small notchesand drive iron `rests at the points I wish to retain the sash.

Then to move it from one point to another,

I press the long leg of said angle, and said l har together, and move the window sash at pleasure.

W hat I claim as my invention, and desire to secure by Letters Patent, is

The application of a spring to an angle that plays upon a pivot, and passing such angle through the stile of the window sash as herein describedfor the purpose of retaining widow sashes at any given point, and making windows, fast and'secure when closed. v

JONATHAN BACON.
